Abstract

The population structure of Chondrostoma fahirae (Ladiges, 1960) was studied based on 85 specimens. Males made up 60.0% (51) and females 40.0% (34) of the population. The length-weight relationship and Von Bertalanffy growth equation were estimated as W = 0.019 x L 3.0761 r = 0.983, L t = 15.62 (1 – e –0.17 ( t+3.06) ), respectively. Gammarus pulex, aquatic insects and Ochrophyta are the major food resources for C. fahirae. Water abstraction and agricultural pollution has led to the near extirpation of the species at its type locality Başpınar Spring.
